DRAFT-EQUALIZER.

SPECIFICATION formingpart of Letters Ittent NO. 454,892, dated. June 30, 1891.

Application filed March 12, 1891- Serial No. 384,811. (No model.)

' ers, of which the following is a specification,

reference being had therein to the accompanying drawing and the letters of reference thereon, formingapart of this specification, in which The drawing represents a top plan view of the draft-equalizer as it would appear adapted to use with four horses.

Referring to the drawing, H represents the principal doubletree pivoted to the outer end of a bracket S, secured to the side of a poleA of either a vehicle or a reaping or mowing machine, and held on said bracket by means of a bolt and the strap 'v in the ordinary manner, but nearer one end than the other.

J is a doubletree connected to the short end,

of doubletree H by means of the lever L. The forward end of said lever is pivoted to the doubletree J, and is also pivoted near its center to the short end of doubletree H, and its rear extending end projects beyond said doubletree and is provided at that end with the row of holes 1' for receiving the hooked end of the rod F. The doubletree has attached to its short end by means of the strap 0 the whifiletree w and to its opposite end the doubletree K, to which is attached the whifiietrees w w. The long end of doubletree H has attached to it by means of the strap N the whiffletree P. The long end of doubletree H is connected with the rear end of the pole A at some little distance from the rear of said doubletree by means of the rods B and D, connected about opposite the center of said doubletree by means of a link or ring 00, and said ring is connected with the doubletree J i at its point of pivot with the lever L by means of the rod E, and the rear end of said lever is connected with doubletree K by means of the rod F and cord or chain G, the said cord passing over a friction-wheel agarranged in the extending long end of doubletree J. The rod F is hooked on its rear end, and maybe inserted into anyone of the holes 2' to adjust it along on said lever, which adj ustment is for the purpose of furnishing means for varying the power applied to either end of the doubletree J. By connecting the .doubletree J with the rods B and D at X, as

shown, the doubletree J is connected with doubletree H at two different points or at each end and in such yielding manner as to permit the free Working of said doubletree and a lateral movement of doubletree J to some little extent, permitted by said lever L, for the purpose of adjusting the device to the power that maybe applied to the outer long end of doubletree H and to doubletree J without the necessity of changing the location or position of the parts. If desired, more or less horses may be used with the device simply by changing the number of Whiffletrees.

Having thus described my invention, What I claimas new, and desire to secure by Letters Patent, is as follows, to wit:

The draft-equalizer shown and described, consisting of the combination, with the pole A, having the bracket S, of the doubletree H, rods B D, and link 00 for connecting the rear end of the pole and long end of said doubletree, doubletree J, having the friction-Wheel r, lever L, having the holes 1' for connecting said doubletrees, rod E and cord G for connecting doubletree K with the rear end of lever L, and doubletree K, all arranged to operate substantially as and for the purpose set forth.
